My Ender 3 Printer was working fine before, but recently an error Thermal Runaway E1 has been showing up and halting my prints, really in the first couple of minutes.
I have done a bit of research and :
I replaced the Thermistor
I ran a PID autotune via Pronterface, which worked fine 2 out of the 3 times I attempted this.
After these changes, I still sometimes get Thermal Runaway E1 Error, and most other times I get ‘Heat Failure’ E1. It seems that the problem is in the nozzle temperature, and for some reason the temperature stops increasing about ten degrees from the temperature that it is set to reach.
For example:
If I set the nozzle temperature at 240 degrees,
The nozzle will start decreasing temperature at about 230 degrees, and the
‘Heat Failure’ error will be triggered.
If I set the nozzle temp at 220 degrees,
The nozzle will start decreasing temperature at about 210 degrees, and the
'Heat Failure' error will be triggered.
Has anyone else had this issue with Ender 3? I keep checking wires to see if that’s the issue, but it all looks fine, everything is attached to the right spots and secure. The nozzle does get hot, so I don’t think my heat cartridge is the problem. I’ve changed the thermistor twice, so I don’t think that’s the issue either. I feel like it must be something off in the calibration (my printer came with Marlin), but I’m not sure how to change that.
I’d check the the heat cartridge or just replace it with one from amazon (hey if that doesn’t solve the issue you can always return it). Our you will need to check the resistance of the heat cart so bust out that multimeter.
If the it happens again after the cartridge change. There might be a broken wire in the sensor wire. I’m not sure if the creality is home run in terms of wires or if the wires go to a connector then to the board.
I would suggest changing the heater cartridge as well. Especially if you’ve already changed the thermistor. Also, make sure all the cables are connected firmly to the board. If it still causes an error after that then the board will need replacing. There are a lot better upgradeable boards out there if that’s the case. I prefer BTT SKR line of boards.
so i have a gantry 3d printer and its like a cheaper version of ender when i ordered it years ago amazone sent me 3 of them by accident lol but i didnt realize till i put one together and i got a heating error i told amazone it was not working they was ok and said send it back but when i grab the box agian im like why it so tall but shallow and have weight then i seen it was 3 of the plain boxes tapped together and i told amazon they said keep them thats when i knew this printer must suck but any ways i got back to trying to use the one good one heating failed but i took it apart changed the thermostat and heating element even the pcb board nothing untill i took the housing holding the 3 fans off and it heated up fine i notice i turned the fans off but the middle one stayed running so no setting for that i think the middle one is to keep the heat from going up and melting wires but the made it too strong now im sad because i would of had 2 more printers lol not mad mad tho becauce i turned one into a cnc for pcb
but my fix is to cut all 3 fans and wire the main to one of the sides so i can turn it down to do it job right i almost never print with the cooling fans on but if i need to ill add part to derrect the fan im using to the print
ill let you know if it works so me saying my fix is that it not fixed yet just me about to test it
yeah so after doing some test my main fan is not working right plus its to strong to be the main one after wiring it to the side ones where i can control it wont turn on till after 100 + but that 100 setting i gave it was less then what the main wire was giving it so i dont get the error
